Description

Tête de distribution de produit cosmétique comprenant un organe de raclage, et dispositif de conditionnement associé  Cosmetic product dispensing head comprising a scraper member and associated conditioning device
La présente invention concerne une tête de distribution de produit cosmétique, du type comprenant :  The present invention relates to a cosmetic product dispensing head, of the type comprising:
- un organe de distribution du produit cosmétique, présentant un conduit tubulaire définissant un passage pour le produit cosmétique, le conduit présentant une face externe orientée à l'opposée du passage, et  a dispensing member of the cosmetic product, having a tubular duct defining a passage for the cosmetic product, the duct having an external face oriented opposite the passage, and
- un bouchon d'obturation du passage, déplaçable entre une position de libération du passage et une position d'obturation du passage, le bouchon comprenant un doigt s'étendant dans le passage lorsque le bouchon est en position d'obturation et une jupe s'étendant autour du conduit lorsque le bouchon est en position d'obturation, la jupe présentant une face interne orientée vers le doigt,  a plug for closing the passage, movable between a position for releasing the passage and a position for closing the passage, the stopper comprising a finger extending in the passage when the stopper is in the closed position and a skirt extending around the duct when the cap is in the closed position, the skirt having an internal face facing towards the finger,
la face externe du conduit et la face interne de la jupe présentant des moyens complémentaires de coopération pour la solidarisation du bouchon à l'organe de distribution,  the outer face of the duct and the inner face of the skirt having complementary means of cooperation for securing the plug to the dispenser member,
L'invention concerne également un dispositif de conditionnement de produit cosmétique fermé par une telle tête de distribution.  The invention also relates to a cosmetic product conditioning device closed by such a dispensing head.
On connaît des têtes de distribution de produit cosmétique du type précité. De telles têtes sont généralement utilisées pour fermer le réservoir d'un dispositif de conditionnement d'un produit cosmétique, par exemple un produit capillaire, ou un produit d'hygiène, ou un produit de soin du visage et/ou du corps, ou un produit de maquillage, ou un produit solaire, de façon à évider l'oxydation ou la perte d'actifs dudit produit cosmétique. Elles permettent également, lorsque le bouchon est en position de libération, la sortie du produit cosmétique hors du réservoir à travers le passage de l'organe de distribution, pour l'utilisation du produit cosmétique par un utilisateur.  Cosmetic product dispensing heads of the aforementioned type are known. Such heads are generally used to close the reservoir of a device for packaging a cosmetic product, for example a hair product, or a hygiene product, or a product for the care of the face and / or the body, or a makeup product, or a solar product, so as to evade the oxidation or loss of assets of said cosmetic product. They also allow, when the cap is in the release position, the outlet of the cosmetic product out of the reservoir through the passage of the dispensing member, for the use of the cosmetic product by a user.
Le produit cosmétique est plus généralement est un produit tel que défini dans le Règlement CE N ° 1223/2009 du Parlement européen etdu Conseil daté du 30 novembre 2009, relatif aux produits cosmétiques.  The cosmetic product is more generally a product as defined in Regulation EC No. 1223/2009 of the European Parliament and of the Council dated 30 November 2009 on cosmetic products.
Il est cependant difficile de réaliser une étanchéité de bonne qualité entre le bouchon et l'organe de distribution. En conséquence, le produit cosmétique contenu dans le dispositif de conditionnement a tendance à s'oxyder, même lorsque le bouchon est en position d'obturation. Cette oxydation est particulièrement sensible au niveau du produit cosmétique qui s'est déposé dans le passage. L'esthétique et la performance du produit cosmétique en sont diminuées.  However, it is difficult to achieve a good seal between the cap and the dispenser member. As a result, the cosmetic product contained in the packaging device tends to oxidize, even when the cap is in the closed position. This oxidation is particularly sensitive at the level of the cosmetic product that has deposited in the passage. The aesthetics and the performance of the cosmetic product are diminished.
En outre, des résidus d'aspect peu agréable pour l'utilisateur sont susceptibles de se former dans le passage ou à l'extérieur de la tête de distribution. Un objectif de l'invention est de réduire les risques d'oxydation d'un produit cosmétique contenu dans un dispositif de conditionnement. Un autre objectif est de limiter les coûts de production nécessaires à la résolution du problème technique précité. In addition, residues of unattractive appearance for the user are likely to form in the passage or outside of the dispensing head. An object of the invention is to reduce the risk of oxidation of a cosmetic product contained in a packaging device. Another objective is to limit the production costs necessary to solve the aforementioned technical problem.
A cet effet, l'invention a pour objet une tête de distribution du type précité, dans laquelle le doigt porte un organe de raclage périphérique faisant saillie radialement depuis une face périphérique du doigt, l'organe de raclage présentant au moins une ligne de pourtour adaptée pour être en contact avec le conduit lorsque le bouchon est en position d'obturation.  For this purpose, the subject of the invention is a dispensing head of the aforementioned type, in which the finger bears a peripheral scraping member projecting radially from a peripheral face of the finger, the scraping member having at least one circumferential line. adapted to be in contact with the duct when the cap is in the closed position.
Dans des modes de réalisation particuliers de l'invention, la tête de distribution présente en outre l'une ou plusieurs des caractéristiques suivantes, prise(s) isolément ou suivant toute(s) combinaison(s) techniquement possible(s) :  In particular embodiments of the invention, the dispensing head furthermore has one or more of the following characteristics, taken in isolation or according to any combination (s) technically possible (s):

D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description qui va suivre, donnée uniquement à titre d'exemple et faite en se référant aux dessins annexés, dans lesquels :  Other features and advantages of the invention will appear on reading the description which follows, given solely by way of example and with reference to the appended drawings, in which:
la Figure 1 est une vue axiale en coupe d'un dispositif de conditionnement de produit cosmétique selon l'invention, préalablement à sa première utilisation, la Figure 2 est une vue similaire à la Figure 1 , le bouchon étant dans une position d'introduction du bouchon dans le passage de produit cosmétique, et - la Figure 3 est une vue similaire à la Figure 1 , le bouchon étant en position d'obturation du passage.  Figure 1 is an axial sectional view of a cosmetic product conditioning device according to the invention, prior to its first use, Figure 2 is a view similar to Figure 1, the plug being in a position of introduction plug in the cosmetic product passage, and - Figure 3 is a view similar to Figure 1, the plug being in the closed position of the passage.
Le dispositif de conditionnement 10 est destiné au conditionnement de produit cosmétique. Il comprend un réservoir 12 contenant un produit cosmétique 14, typiquement un produit de coloration, un produit capillaire, un produit d'hygiène, un produit de soin du visage et/ou du corps, un produit de maquillage, ou un produit solaire.  The packaging device 10 is intended for the packaging of cosmetic product. It comprises a reservoir 12 containing a cosmetic product 14, typically a coloring product, a hair product, a personal care product, a facial and / or body care product, a makeup product, or a solar product.
Ce réservoir 12 présente une paroi tubulaire 20 et un fond 22 fermant la paroi tubulaire 20 à une première extrémité 24. La deuxième extrémité 26 de la paroi 20, opposée à l'extrémité 24, délimite une ouverture 28 pour la sortie du produit cosmétique 14 hors du réservoir 12. A cet effet, l'ouverture 28 communique avec l'intérieur et l'extérieur du réservoir 12.  This reservoir 12 has a tubular wall 20 and a bottom 22 closing the tubular wall 20 at a first end 24. The second end 26 of the wall 20, opposite the end 24, defines an opening 28 for the output of the cosmetic product 14 out of the tank 12. For this purpose, the opening 28 communicates with the inside and the outside of the tank 12.
La paroi tubulaire 20 a de préférence une section radiale, c'est-à-dire prise selon un plan perpendiculaire à l'axe du tube, circulaire ou ovale.  The tubular wall 20 preferably has a radial section, that is to say taken in a plane perpendicular to the axis of the tube, circular or oval.
L'axe de l'ouverture 28 est orienté sensiblement parallèlement à l'axe de la paroi 20. En particulier, il est sensiblement confondu avec ledit axe.  The axis of the opening 28 is oriented substantially parallel to the axis of the wall 20. In particular, it is substantially coincident with said axis.
Dans l'exemple représenté, l'extrémité 26 de la paroi 20 est recourbée vers l'axe de la paroi tubulaire 20. Le dispositif de conditionnement 10 comprend en outre une tête de distribution 30 fermant le réservoir 12. En d'autres termes, la tête de distribution 30 s'étend en travers de l'ouverture 28 de façon à obstruer l'ouverture 28. In the example shown, the end 26 of the wall 20 is bent towards the axis of the tubular wall 20. The conditioning device 10 further comprises a dispensing head 30 closing the reservoir 12. In other words, the dispensing head 30 extends across the opening 28 so as to obstruct the opening 28.
La tête de distribution 30 comprend un organe de distribution 32 solidaire du réservoir 12. Cet organe de distribution 32 comprend un conduit tubulaire 34 définissant un passage 36 axial pour le produit cosmétique 14, et une jupe 38 faisant saillie radialement vers l'extérieur depuis le conduit tubulaire 34.  The dispensing head 30 comprises a dispensing member 32 integral with the reservoir 12. This dispensing member 32 comprises a tubular duct 34 defining an axial passage 36 for the cosmetic product 14, and a skirt 38 projecting radially outwardly from the tubular duct 34.
Le conduit tubulaire 34 a en particulier une section radiale sensiblement constante. The tubular duct 34 has in particular a substantially constant radial section.
Dans cet exemple, le conduit tubulaire 34 est rectiligne. In this example, the tubular duct 34 is rectilinear.
Le conduit tubulaire 34 présente une extrémité 40 de raccordement du passage 36 au réservoir 12, et une extrémité 42 opposée de sortie du produit cosmétique 14 hors du dispositif de conditionnement 10. Le passage 36 débouche à l'intérieur du dispositif de conditionnement 10 par l'extrémité 40, et à l'extérieur du dispositif de conditionnement 10 par l'extrémité 42  The tubular duct 34 has an end 40 for connecting the passage 36 to the reservoir 12, and an opposite end 42 for the exit of the cosmetic product 14 from the conditioning device 10. The passage 36 opens into the interior of the conditioning device 10 via the end 40, and outside the conditioning device 10 by the end 42
Le conduit tubulaire 34 comprend un tronçon 44 s'étendant d'un côté de la jupe The tubular duct 34 comprises a section 44 extending on one side of the skirt
38. Dans l'exemple représenté, le conduit tubulaire 34 est constitué par ledit tronçon 44, c'est-à-dire que le conduit tubulaire 34 s'étend intégralement d'un seul côté de la jupe 38. En d'autres termes, la jupe 38 fait saillie depuis une extrémité du conduit tubulaire 34, en particulier depuis l'extrémité de raccordement 40. 38. In the example shown, the tubular duct 34 is constituted by said section 44, that is to say that the tubular duct 34 extends integrally on one side of the skirt 38. In other words the skirt 38 projects from one end of the tubular duct 34, in particular from the connecting end 40.
Le conduit tubulaire 34 présente en outre une face interne 46 définissant le passage 36, et une face externe 48 orientée à l'opposée du passage 36. La face interne 46 est lisse.  The tubular conduit 34 further has an inner face 46 defining the passage 36, and an outer face 48 facing the opposite of the passage 36. The inner face 46 is smooth.
La jupe 38 est partiellement insérée dans le réservoir 12. Son bord périphérique 50 coopère avec la deuxième extrémité 26 de la paroi 20 pour empêcher le retrait de la jupe 38 hors du réservoir 12. A cet effet, la face extérieure du bord périphérique 50 est par exemple collée à la face intérieure de la deuxième extrémité 26.  The skirt 38 is partially inserted into the reservoir 12. Its peripheral edge 50 cooperates with the second end 26 of the wall 20 to prevent the withdrawal of the skirt 38 from the reservoir 12. For this purpose, the outer face of the peripheral edge 50 is for example glued to the inner face of the second end 26.
Le bord périphérique 50 est recourbé à l'opposé du tronçon 44 du conduit 34. The peripheral edge 50 is curved away from the section 44 of the duct 34.
La jupe 38 est sensiblement coaxiale au conduit 34. The skirt 38 is substantially coaxial with the duct 34.
L'organe de distribution 32 comprend en outre une saillie annulaire 52 faisant saillie radialement depuis le conduit 34, en particulier depuis l'extrémité de raccordement 40 du conduit 34, vers l'intérieur du passage 36. Elle définit dans le passage 36 un épaulement 54 orienté vers l'extrémité de sortie 42. Ledit épaulement 54 a, dans l'exemple représenté, une forme de tronc de cône ayant pour axe l'axe du passage 36 et rétrécissant vers l'extrémité de raccordement 40.  The dispensing member 32 further comprises an annular projection 52 projecting radially from the duct 34, in particular from the connecting end 40 of the duct 34, towards the interior of the passage 36. It defines in the passage 36 a shoulder 54, which is oriented towards the outlet end 42. Said shoulder 54 has, in the example shown, a conical frustum shape having the axis of the passage 36 as a axis and narrowing towards the connecting end 40.
L'organe de distribution 32 est de préférence monobloc. La tête de distribution 30 comprend en outre un opercule 56 étanche à l'air et aux fluides. Cet opercule 56 est surmoulé de manière étanche à l'organe de distribution 30 et s'étend en regard du passage 36. Il empêche ainsi le produit cosmétique 14 de s'écouler hors du réservoir 12 par le passage 36, et empêche l'air de pénétrer dans le réservoir 12 par l'intermédiaire du passage 36. The dispensing member 32 is preferably monobloc. The dispensing head 30 further comprises a lid 56 impervious to air and fluids. This cover 56 is molded tightly to the dispensing member 30 and extends opposite the passage 36. It thus prevents the cosmetic product 14 from flowing out of the reservoir 12 through the passage 36, and prevents the air to enter the reservoir 12 via the passage 36.
Dans l'exemple représenté, l'opercule 56 est surmoulé sur la face intérieure de la jupe 38, orientée vers l'intérieur du réservoir 12.  In the example shown, the cover 56 is overmolded on the inner face of the skirt 38, facing the inside of the reservoir 12.
En variante, l'opercule 56 ne s'étend pas en regard mais en travers du passage 36. L'opercule 56 est alors scellé au conduit tubulaire 34. Les avantages sont les mêmes que ceux indiqués précédemment.  Alternatively, the cover 56 does not extend opposite but across the passage 36. The cover 56 is then sealed to the tubular conduit 34. The advantages are the same as those indicated above.
L'opercule 56 est en particulier une membrane en matériau plastique ou associant un matériau plastique à du métal.  The operculum 56 is in particular a membrane made of plastic material or associating a plastic material with metal.
La tête de distribution 30 comprend en outre un bouchon 60. Ce bouchon 60 est déplaçable entre une position de libération du passage 36, dans laquelle en particulier le bouchon 60 est à l'écart du conduit 34, pour permettre la sortie du produit cosmétique 14 par le passage 36, et une position d'obturation du passage 36, dans laquelle en particulier le bouchon 60 s'étend en travers du passage 36, pour empêcher la sortie du produit cosmétique 14 par le passage 36.  The dispensing head 30 further comprises a plug 60. This plug 60 is movable between a position of release of the passage 36, in which in particular the plug 60 is away from the conduit 34, to allow the exit of the cosmetic product 14 through the passage 36, and a closed position of the passage 36, in which in particular the plug 60 extends across the passage 36, to prevent the output of the cosmetic product 14 through the passage 36.
Le bouchon 60 est représenté dans sa position d'obturation sur la Figure 3. Dans cette position d'obturation, le bouchon 60 obture le passage 36 de manière étanche à l'air et aux liquides.  The plug 60 is shown in its closed position in Figure 3. In this closed position, the plug 60 closes the passage 36 in a sealed manner to air and liquids.
Le bouchon 60 est de préférence monobloc. Il comprend un doigt creux 62 et une jupe 64 sensiblement coaxiale avec le doigt 62 et s'étendant autour du doigt 62.  The cap 60 is preferably monobloc. It comprises a hollow finger 62 and a skirt 64 substantially coaxial with the finger 62 and extending around the finger 62.
Le doigt 62 est adapté pour s'étendre à l'intérieur du passage 36 lorsque le bouchon 60 est en position d'obturation. A cet effet, le diamètre extérieur du doigt 62 est inférieur au diamètre du passage 36.  The finger 62 is adapted to extend inside the passage 36 when the cap 60 is in the closed position. For this purpose, the outside diameter of the finger 62 is smaller than the diameter of the passage 36.
Le doigt 62 présente une extrémité 66 de jonction à la jupe 64, et une extrémité libre 68. L'extrémité libre 68 est adaptée pour perforer l'opercule 56 lorsque le bouchon 60 est en position d'obturation. Cela permet de libérer le passage 36 pour autoriser la sortie du produit cosmétique 14 par le passage 36. A cet effet, l'extrémité libre 68 est à une distance de l'extrémité de jonction 66 supérieure à la longueur axiale du passage 36. En outre, l'extrémité libre 68 est biseautée, de façon à faciliter la perforation de l'opercule 56.  The finger 62 has an end 66 joining the skirt 64, and a free end 68. The free end 68 is adapted to perforate the cap 56 when the cap 60 is in the closed position. This makes it possible to release the passage 36 to allow the cosmetic product 14 to exit the passage 36. For this purpose, the free end 68 is at a distance from the junction end 66 greater than the axial length of the passage 36. in addition, the free end 68 is beveled, so as to facilitate the perforation of the cover 56.
Le doigt 62 porte par ailleurs un organe de raclage 70 périphérique, faisant saillie radialement vers l'extérieur depuis une face périphérique 72 du doigt 62. Cet organe de raclage 70 a en particulier un diamètre sensiblement égal au diamètre du passage 36. L'organe de raclage 70 présente une ligne de pourtour 74 adaptée pour être intégralement en contact avec le conduit 34 lorsque le doigt 62 s'étend dans le passage 36. Cette ligne de pourtour 74 est en particulier fermée et continue. The finger 62 also carries a scraper device 70 projecting radially outwardly from a peripheral face 72 of the finger 62. This scraper member 70 has in particular a diameter substantially equal to the diameter of the passage 36. The scraper member 70 has a peripheral line 74 adapted to be in full contact with the duct 34 when the finger 62 extends in the passage 36. This peripheral line 74 is in particular closed and continuous.
La ligne de pourtour 74 s'étend de préférence, comme représenté, dans un plan radial sensiblement perpendiculaire à l'axe du doigt 62.  The peripheral line 74 preferably extends, as shown, in a radial plane substantially perpendicular to the axis of the finger 62.
Dans l'exemple représenté, l'organe de raclage 70 est une lèvre annulaire coaxiale au doigt 62 et s'étendant autour du doigt 62. Ladite lèvre présente une épaisseur sensiblement égale à la largeur de l'intervalle annulaire 76 laissé libre entre le doigt 62 et le conduit 34 lorsque le bouchon 60 est en position d'obturation. La ligne de pourtour 74 est formée par le bord libre de la lèvre.  In the example shown, the scraper member 70 is an annular lip coaxial with the finger 62 and extending around the finger 62. Said lip has a thickness substantially equal to the width of the annular gap 76 left free between the finger 62 and the duct 34 when the cap 60 is in the closed position. The circumferential line 74 is formed by the free edge of the lip.
La ligne de pourtour 74 est plus proche de l'extrémité libre 68 du doigt 62 que de l'extrémité de jonction 66.  The circumferential line 74 is closer to the free end 68 of the finger 62 than to the junction end 66.
La distance de l'organe de raclage 70 à l'extrémité libre 68 est en particulier choisie de sorte que l'organe de raclage 70 soit en contact avec l'épaulement 54 le long d'une ligne de contour fermée lorsque le bouchon 60 est en position d'obturation.  The distance from the scraper member 70 to the free end 68 is chosen in particular so that the scraper member 70 is in contact with the shoulder 54 along a closed contour line when the cap 60 is in the closed position.
L'organe de raclage 70 est de préférence venu de matière avec le doigt 62.  The scraper member 70 is preferably integral with the finger 62.
La jupe 64 est adaptée pour s'étendre autour du conduit 34 lorsque le bouchon 60 est en position d'obturation. A cet effet, le diamètre intérieur de la jupe 64 est supérieur au diamètre extérieur du conduit 34.  The skirt 64 is adapted to extend around the duct 34 when the cap 60 is in the closed position. For this purpose, the inside diameter of the skirt 64 is greater than the outside diameter of the duct 34.
La jupe 64 présente une face interne 78 orientée vers le doigt 62. Cette face interne 78 présente, avec la face externe 48 du conduit 34, des moyens complémentaires 80, 82 de coopération pour la solidarisation du bouchon 60 à l'organe de distribution 32 lorsque le bouchon 60 est en position d'obturation. Ces moyens complémentaires 80, 82 comprennent, dans l'exemple représenté, un filetage 80 sur la face externe 48 du conduit 34 et un taraudage 82 sur la face interne 78 de la jupe 64.  The skirt 64 has an internal face 78 facing the finger 62. This inner face 78 has, with the outer face 48 of the duct 34, complementary means 80, 82 for cooperation for securing the cap 60 to the dispenser member 32 when the cap 60 is in the closed position. These complementary means 80, 82 comprise, in the example shown, a threading 80 on the outer face 48 of the duct 34 and a threading 82 on the inner face 78 of the skirt 64.
La tête de distribution 30 comprend encore une bague de sécurité 86 amovible adaptée pour maintenir le bouchon 60 dans une position intermédiaire (Figure 1 ) entre ses positions d'obturation et de libération, dans laquelle le doigt 62 est engagé dans le passage 36, son extrémité libre 68 étant à distance de l'opercule 56. Cela permet d'éviter que l'opercule 56 ne soit percé involontairement avant la première utilisation du produit cosmétique 14. Le produit cosmétique 14 est ainsi mieux préservé de l'oxydation.  The dispensing head 30 also comprises a removable safety ring 86 adapted to hold the plug 60 in an intermediate position (FIG. 1) between its closed and release positions, in which the finger 62 is engaged in the passage 36, its free end 68 being at a distance from the cover 56. This prevents the operculum 56 from being pierced involuntarily before the first use of the cosmetic product 14. The cosmetic product 14 is thus better preserved from oxidation.
La bague de sécurité 86 est fixée par des moyens de fixation frangibles (non représentés) au bord libre 88 de la jupe 64 et à l'organe de distribution 32. Elle entoure le conduit 34 et est interposée entre la jupe 64 du bouchon 60 et la jupe 38 de l'organe de distribution 32. La bague 86 rend ainsi impossible tout déplacement du bouchon 60 vers l'opercule 56. En outre, grâce aux moyens d'attache frangibles, elle maintient le bouchon 60 attaché à l'organe de distribution 32, ce qui évite la perte du bouchon 60. The safety ring 86 is fixed by frangible attachment means (not shown) to the free edge 88 of the skirt 64 and to the dispensing member 32. It surrounds the duct 34 and is interposed between the skirt 64 of the cap 60 and the skirt 38 of the dispensing member 32. The ring 86 thus makes it impossible to move the cap 60 towards In addition, thanks to the frangible attachment means, it keeps the cap 60 attached to the dispensing member 32, which prevents the loss of the stopper 60.
Le dispositif de conditionnement 10 est utilisé de la manière décrite ci-dessous. The conditioning device 10 is used as described below.
Tout d'abord, le dispositif de conditionnement 10 est fourni avec la bague de sécurité 86 maintenant le bouchon 60 dans sa position intermédiaire, comme illustré sur la Figure 1 . First, the conditioning device 10 is provided with the safety ring 86 holding the cap 60 in its intermediate position, as illustrated in FIG.
L'utilisateur commence par faire tourner le bouchon 60 de façon à le dévisser. Ce faisant, il sollicite les moyens d'attache frangibles de la bague 86, qui rompent. Le bouchon 60 est déplacé en position de libération et l'utilisateur finit de détacher la bague 86 de l'élément auquel elle était restée attachée.  The user begins by turning the cap 60 so as to unscrew it. In doing so, it solicits the frangible attachment means of the ring 86, which break. The cap 60 is moved to the release position and the user finishes detaching the ring 86 from the element to which it had remained attached.
Le bouchon 60 est ensuite repositionné sur l'organe de distribution 32, comme illustré sur la Figure 2. Lors de ce repositionnement, le doigt 62 du bouchon 60 est introduit dans le passage 36 par l'extrémité de sortie 42 du conduit 34.  The plug 60 is then repositioned on the dispenser member 32, as illustrated in FIG. 2. During this repositioning, the finger 62 of the plug 60 is introduced into the passage 36 through the outlet end 42 of the duct 34.
Le bouchon 60 est alors vissé sur l'organe de distribution 32, jusqu'à atteindre sa position d'obturation. Ce faisant, l'extrémité libre 68 du doigt 62 vient appuyer sur l'opercule 56 et, grâce à l'affûtage de l'extrémité libre 68 en biseau et à la rotation du bouchon 60, l'opercule 56 cède. En particulier, une portion de l'opercule 56 est découpée et tombe au fond du réservoir 12.  The cap 60 is then screwed onto the dispenser member 32 until it reaches its closed position. In doing so, the free end 68 of the finger 62 presses on the cover 56 and, thanks to the sharpening of the free end 68 in bevel and the rotation of the plug 60, the operculum 56 gives way. In particular, a portion of the lid 56 is cut and falls to the bottom of the tank 12.
Le produit cosmétique 14 est alors prêt à être utilisé.  The cosmetic product 14 is then ready to be used.
A cet effet, l'utilisateur dévisse à nouveau le bouchon 60 jusqu'à le ramener en position de libération, puis incline le dispositif 10 pour verser le produit cosmétique 14 à l'extérieur du dispositif de conditionnement 10.  For this purpose, the user again unscrews the cap 60 to bring it back into the release position, then tilts the device 10 to pour the cosmetic product 14 outside the conditioning device 10.
Une fois la dose de produit 14 désirée versée, le bouchon 60 est replacé sur l'organe de distribution 32, puis revissé en position d'obturation. Ce faisant, l'organe de raclage 70 frotte le long de sa ligne de pourtour 74 contre le conduit 34 et entraîne avec lui, vers le réservoir 12, le produit cosmétique qui s'était déposé à l'intérieur du passage 36.  Once the dose of product 14 desired poured, the cap 60 is placed on the dispenser member 32, and then returned to the closed position. In doing so, the scraper member 70 rubs along its peripheral line 74 against the duct 34 and carries with it, towards the reservoir 12, the cosmetic product which had been deposited inside the passage 36.
En prenant appui contre l'épaulement 54 en fin de course, l'organe de raclage 70 assure une bonne étanchéité vis-à-vis de l'air et des fluides. Le produit cosmétique 14 restant dans le réservoir 12 demeure ainsi à l'abri de l'oxydation, malgré la rupture de l'opercule 56.  By bearing against the shoulder 54 at the end of the stroke, the scraper member 70 provides a good seal against air and fluids. The cosmetic product 14 remaining in the reservoir 12 thus remains safe from oxidation, despite the rupture of the operculum 56.
Grâce à l'invention décrite ci-dessus, le produit cosmétique 14 est mieux protégé de l'oxydation. En particulier, l'oxydation de produit cosmétique demeuré dans le passage 36 est empêchée. En outre, cet avantage est obtenu sans que les modifications apportées au dispositif de conditionnement 10 n'occasionnent une augmentation sensible de ses coûts de production. Thanks to the invention described above, the cosmetic product 14 is better protected from oxidation. In particular, the oxidation of cosmetic product remaining in the passage 36 is prevented. In addition, this advantage is obtained without the modifications made to the packaging device 10 causing a significant increase in its production costs.
